An experimental research is presented which is aimed at evaluating the capability of an experimental modal analysis to assess the stiffness decrease due to damage, as well as the stiffness recovery due to strengthening. Ten beams were tested. All of them were subjected to loading cycles with increasing load levels in order to induce cracking of different severity in them. The beams were then retrofitted by externally bonded FRP sheets. Three types of composites were used. The number of layers was varied, too. Modal tests were carried out after each loading-unloading cycle. The modal frequencies and damping ratios were determined for the first four vibration modes. The results obtained indicate that an experimental modal analysis can give useful information on the severity of amage and the effectiveness of strengthening.14aDYNAMICS14aSTIFFNESS14aREINFORCED CONCRETE14aFRP14aREPAIR14aSTRENGTHENING14aIDENTIFICATION14aCRACKING12aBonfiglioli, B.12aPascale, G.40uhttps://drive.google.com/file/d/1oNqVdBMz58YXm2FU1rE9AnQ8z47e1IVy/view?usp=drivesdkzPara ver el documento ingresa a Google con tu cuenta: @cicy.edu.mx  2LoccREF1250602s9999    xx |||||s2   |||| ||und|d  c17914d17914  00102Loc40708F1aCICYbCICYcREd2025-06-25l0oB-7651r2025-06-25 12:47:05w2025-06-25yREF1
